Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. The products and the method are chosen for how heavily each space is used.

How the job changes by surface

Healthcare and care settings

We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we’ll confirm with the quote.

Showers and trays

If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Newtown may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Getting the site ready

  • Point out parking and an unloading spot
  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Advice

Commercial washrooms in Newtown

Newtown lies roughly 60 miles out from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

At a hospital like Knowle Hospital, 3.8 miles south-west of Newtown, patient and staff washrooms are best done in short phases agreed with the ward. Where you’re responsible for a hall attached to a building such as Church of the Holy Trinity, its kitchen and toilets need sealant that stays cleanable. At a school such as Newtown Soberton Infant School, changing rooms and kitchens need cleanable joints as much as the toilets.

Newtown is about 5 miles north-west of Waterlooville, in Hampshire. Across the PO17 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places. We also cover Portsmouth, some 8 miles away.

Postcode districts covered here: PO17. For a building on Church Road, Hundred Acres Road and Ingoldfield Lane or nearby, we can quote for washrooms and wet areas. We also cover Southend (1 mile north-east), Soberton Heath (1 mile north), Hoe Gate (1 mile east), Hipley (1 mile south-east) and Woodend (1 mile north-west). Bigger towns within reach include Winchester (13 miles north-west), Gosport (8 miles south), Havant (7 miles south-east), Eastleigh (10 miles west), Fareham (5 miles south-west) and Horndean (5 miles east).

In Newtown, that means premises near The Bold Forester Public House, among other places. For rail, the closest station is Portchester station, about 4.4 miles south of the centre. Other landmarks nearby include Knowle Hospital (3.8 miles south-west). Open spaces near Newtown include St Clair's Meadow and Portsdown Hill.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

After the work

Regular inspection catches problems early. In particular:

  • Leave signs up until the cure time is over
  • Photograph and log failed joints across the estate
  • Include joints in routine washroom inspections
  • Act on the first split you see at a shower tray

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Owners, agents and contractors

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

FAQs: Newtown

Can you take on a job at a hospital such as Knowle Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Will all the washrooms in our Newtown building be closed at once?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Can you quote from photographs?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Will cleaning remove black mould from sealant?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we will set out a timescale with the quote.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Location, for remote and island sites
  • Access and working height
  • Whether old sealant has to be cut out first
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Clear photos of the problem areas
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • Any specification or named product

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
